Pyroelectric material property considerations for x-ray generation
The method of generating x-rays using the pyroelectric effect has garnered interest for applications that desire portability and low power consumption, particularly for real-time in-field and on-line analyses. However, the x-ray intensity produced by this ...
2022Cross verified independent measurements of correlated bubble property distributions as part of the scale-up of a catalytic bubbling fluidized bed reactor
Methanation can be applied as part of a Power-to-Gas (PtG) concept to store renewable electricity. Using a catalytic bubbling fluidized bed (BFB) methanation reactor allows a flexible and economic operation. Properties of bubbles rising through the fluidiz ...
EPFL2022Ion temperature spectroscopic measurements in high rotation discharges by means of X-ray diagnostic at JET
Measurement of the X-ray spectra of the He-like Ni ions (Ni26+) and their dielectronic satellites (Ni25+, Ni24+, and Ni23+) plays a crucial role in determination of electronic and ion temperature of plasma in the JET device. Because n >= 3 satellites of Ni ...
IOP Publishing Ltd2022Learning to sample in Cartesian MRI
Magnetic Resonance Imaging (MRI) is a non-invasive, non-ionizing imaging modality with unmatched soft tissue contrast. However, compared to imaging methods like X-ray radiography, MRI suffers from long scanning times, due to its inherently sequential acqui ...
EPFL2022Carbon K-edge x-ray emission spectroscopy of gas phase ethylenic molecules
Majed Chergui, Camila Bacellar Cases Da Silveira, Rebecca Ann Ingle, Luca Longetti, Thomas Roland Barillot
We report on the C K-edge x-ray absorption spectra and the resonant (RXES) and non-resonant (NXES) x-ray emission spectra of ethylene, allene and butadiene in the gas phase. The RXES and NXES show clear differences for the different molecules. Overall both ...
IOP Publishing Ltd2022High-Resolution Photoemission Study of Neutron-Induced Defects in Amorphous Hydrogenated Silicon Devices
Sylvain Dunand, Matthew James Large, Giulia Rossi
In this paper, by means of high-resolution photoemission, soft X-ray absorption and atomic force microscopy, we investigate, for the first time, the mechanisms of damaging, induced by neutron source, and recovering (after annealing) of p-i-n detector devic ...
MDPI2022Light-Responsive Oligothiophenes Incorporating Photochromic Torsional Switches
Kevin Sivula, Emilie Baudat, Giuseppe Sforazzini, Augustina Jozeliunaite
We present a quaterthiophene and sexithiophene that can reversibly change their effective pi-conjugation length through photoexcitation. The reported compounds make use of light-responsive molecular actuators consisting of an azobenzene attached to a bithi ...
WILEY-V C H VERLAG GMBH2022Hessian Splines For Scanning Transmission X-Ray Microscopy
Michaël Unser, Thomas Jean Debarre
Scanning transmission X-ray microscopy (STXM) produces images in which each pixel value is related to the measured attenuation of an X-ray beam. In practice, the location of the illuminated region does not exactly match the desired uniform pixel grid. This ...
IEEE2020Attosecond transient absorption spooktroscopy: a ghost imaging approach to ultrafast absorption spectroscopy
Christoph Bostedt, Zhaoheng Guo, Jonas Knurr, Andre Al Haddad, Siqi Li
The recent demonstration of isolated attosecond pulses from an X-ray free-electron laser (XFEL) opens the possibility for probing ultrafast electron dynamics at X-ray wavelengths. An established experimental method for probing ultrafast dynamics is X-ray t ...
